Abstract (en)

A graphene reinforced polyethylene terephthalate composition, comprising a continuous matrix comprising polyethylene terephthalate and graphene nanoplatelets in the form of one or more layers of two-dimensional mono-atomic carbon sheets dispersed within the continuous matrix. The graphene reinforced polyethylene terephthalate composition comprises a concentration of graphene nanoplatelets ranging between 0.005% and 0.1% weight fraction of the graphene reinforced polyethylene terephthalate composition.
